GD880 — High Performance Engineering Drive GD880 — INVT

GD880GD880 Series High-performance Engineering VFD

GD880 — High Performance Engineering Drive INVT

Engineering VFD for heavy industry in two topologies: GD880-11 single drive (400 V 5.5–1,000 kW, 690 V 355–1,200 kW) and a common DC bus multi-drive system. It comprises GD880-71 basic, GD880-81 regenerative and GD880-91 active front-end rectifiers (PF ≥ 0.99, THDi < 5 %), GD880-51 inverters (4–6,500 kW), braking units and a liquid-cooling unit. V/F, SVC and FVC control of induction, PM synchronous and linear motors: ±0.01 % speed accuracy and < 5 ms torque response in FVC. STO SIL 3; CCS type approval for air- and liquid-cooled versions.
